Whenever possible, I try to avoid the treadmill. Sometimes, due to a winter storm advisory -- or pure laziness, it cannot be helped.
I've always suspected that my treadmill wasn't totally accurate and resolved myself to the notion that I just think that I always seem to run faster outside because running inside seems to take the wind out of your sails. But I felt like I was SO much faster outside.
This morning during my run, I decided to use different music, which happened to on the iTouch. So I lauched the NIKE + GPS app and played the music through the app while running.
